This upper layer 21 may, be stitched or Y or strips: 23 are individually movable independently of one another up from the-filler lion which j they'rest and this arrangement provides not only a flexible support for the lower insole upontherubber filler i6 but also for great freedom in ciroulation of air through the slits 22 and beneath I the ribbons or strips 23. It will benoted, particularly from Figure'4,. that the arrangement is such that the lower im sole Isis silpported at substantially a horizontal .alinement orv level with the adjacent part of the dining H where it comes down to meet with such lower'insolea Therefore, the upper insole, the

toe andball portion of which is represented at 24 may be 'made of suflicient lateral span or width to extend over the joint between the lining II and the lower insole liland to conceal this joint and the fastenings' 20" and to elevate the foot. from contact with such joint and fasten- This upper insole,- preferably of leather,isshown in Figures 5 and Sand it is of a composite construction consisting of the ball and toe portion 24 extending oi! the shank portion 25 which adjoins the heel 26. v

" In Figure 5, which shows a top view of the upper insole, the shank and heel portionare shown of duplex thickness havingan upper layer '21 which, however, terminates at the shank portion and does not extend into the toe and ball porotherwise secured to the lower lamination comprising parts 25 and 23. Lines of stitching are indicated at 23 and 23.

As shown in Figure 6 the toefand ball portion 24 is severedpartially at points 30 and 3|. ,These cuts extend from'the oute'r'edges, of the leather inwardly. but an unsevered central neck 32 is left forming the only point of connection between the,

ball and toe portion :4 and the shank portion 25.

This narrow central-neck 32 forms a flexible hinged joint which is disposed opposite the open mouth of a notch 33 made in the forward central portion of the upper layer 21.; This notch-is substantially v-shaped with the widerportion of the V open and.with the apex of'the V rounded off so as to provide a relatively large crotch portion- Com-paring Figures 5 and 6 itwill'be apparent that the cuts 30 and 3]." are made substantially coincident with the straight shoulders 34 and 35;

flanking the notch 33and being substantially transverse of -'the shoe or at rightangles to the shoe length.

The ball portion 24 of the upper insole is pierced by a number of perforations 38. which are grouped together more closely preferably at the toe or tip portion of the shoe. perfora- 'to the shoe 2 the purpose of this construction being to add flexibility to the HD128 in le which is desirable ina compositeinsole such as herein 'shown' and described.

The upper insole is unsecured .to the sole throughout its toe and ball portion 24 but the heel portion may be nailed down-as indicated by the nails 33 in Figure 1; and-at theshank of the shoe the composite or double .layer, upper insolemay be. cemented or otherwise ailixed thereto. At

As shown in G -the toe and ball portion metallic shank stiflener 3! as shown Figures 1 and 2.

In the use or the device, the inner shoeconstruction is composed of the two insoles, the filler lB resting upon the sole I2 and supporting 6' the lower insole i9 and the upper insole 24. Thus the foot or the ball or toe portion thereof is received directly upon the upper insole and sup- .ported'thereby, the weight devolving through the lower insole 19 to the-lower rubber or resilient l filler l6 and thus to the leather outsole l2.

'Ithe rubber filler i6 resiliently supports the foot and also excludes moisture and lends flexibility to the shoe.

Flexibility is also acquired'in the shoe by the i ,slits 22 of lower insole l9 and by the slashings 31 and perforations 36 of the upper insole.

Also air, vapor and moisture may be accommodated in' the slits 22 and in and about and be- .neath the strips 23 and in the perforations 36 and thus the insole construction aiifords pockets for a large volume of air, thus forming in eflfect an air cushion in addition to, the rubber cushion for supporting the foot of the wearer, allto the comfort of the foot. 1

Now when the shoe is removed from the foot it is a simple matter todraw out the toe and ball portion 24 of the upper insole. By inserting the hand in the shoe and underneath one lateral edge .of this toe and .ball portion. 24, the same may be lifted from the lower insole and buckled up in v the center about the neck or tongue 32 which is its only'point of attachment and thata very narrow one; As it is buckled up centrally the outer' free toe portion can be slid backwardly alon 35:

the 'shoe until it clears the upper. Then the' portion 24 may be movedlaterally as indicated in Figure 6 with one-severed end portion 3| rid-'- ing up over its shoulder 34. The narrow neck 32 permits the part 24 to be turned at substan- 40 tially right angles when the free toe portion thereof is slid sufli'ciently far back in order that the edge portion of the part 24 may be drawn outwardly from beneath the upper of the shoe as f it is much easier to draw the part 24 outedgewise than it would be to draw it out flatwise with both of ,its side edges clingingto the narrow upper of the shoe. Thus the narrow neck 32' forms a substantiallycentral and narrow flexible hinge which allows the free part 24 to be flexed to upwardly and laterally in either direction and the cutting away portions 30 and 3| allow "of this flexibility and also permit adjacent portions of the part 24 to slide over the shoulders 34 and 35 whichvare cut away atright angles in order to avoid interference with the-flexing and the turningoftheunsecuredpart24.-- f Thus-the part 24 may be easily and'quickly pulledout of the shoe-v and dra-wncompletely back so that when the shoe is" removed at night so it may be ventilated thoroughly and all the moisture along the part 24 andin the perforations 36 may be evaporated and subject to the passage of the surrounding air; and the air may have free aocesstothe slits 22 and to the spaces'beneath ()5, I

thestrips 23 of the lower insole., In this manner 'the shoe may be rapidly andthoroughly ventilated and dried out. The part 24'may be easfly and quickly reinsertedin the shoe when the shoe isagain-to be i puton.'-

' It will be appreciated from the foregoing that the invention provides in a shoe construction that is not'a turned shoe an improved compound the shank of the shoe there may beprovided a sole construction which produces comfort 1:

children's shoes. It is obvious thatvarious changes and modifications may be made in the details of construe- 10 tion and design of the above specifically described A embodiment of this invention without departing 'iromj the spirit thereof, such changes and modiv, viications being restricted only by the scope oi plete ventilation.

Although the invention has shown and' described'more particularly in connection with ladies shoes", it will be appreciated that the improvement is equally applicable to'mens and to the following claim.

What is claimed is:

prising a bottom rubber flller, a canvas lower insole resting freely and" without attachment upon the rubber bottom filler and having suhstana aoaaeo 1 i3 and flexibility and the advantage of a my tially' transverse slits extending thereacross all the way through said lower insole except in the margin portions thereof whereby to provide independently movable strips between said slits unattached to said rubber bottom filler. means for securing said lower insole to the 'shoe'structure only at the margin portion thereof and an upper insole composed of, a shank-portion se ured to the shoe structure and an unsecured ball and toe part, a narrow intermediate neck between the secured shank portion of the upper insole and the free toe and ball portion thereofwith laterally incised portions of the upper insole at opposite sides of said neck.-the free toe and ball I p'art havingperforations therein and freely rest- In a shoe, an cinner sole construction coming upon the lower insole and being removabl therefrom using said neck as a hinge.
